Only what I found is Dark Juno theme for Eclipse Juno (4.2), you can google it is all over the internet... this one does not seem to wokr out of the box and does not look very nice... I am not a Java guy so, no clue how to edit stuff there

Thanks for the tip, MoonRise dark theme is beatiful, it works far better than the others I previously found!

Despite the limitations of E4 widget styling, it works really well on Ubuntu, OSX and Windows (for OSX I needed to download the package linked in the 'trouble-shooting table' here http: //guari.github.io/eclipse-ui-theme/).
